Display driving device and display device including the same

A display driving device comprising:

• a sense circuit configured to detect pixel signals from pixels of a display panel,
• wherein the sense circuit comprises a sense amplifiers configured to provide a first reference voltage to the pixels so that the pixels are programmed using the first reference voltage in a programming mode,
• wherein each of the pixels comprises:
• an organic light emitting diode (OLED);
• and
• a driving transistor configured to supply a current to the OLED,
• wherein the pixels are programmed using a sum of the first reference voltage and a threshold voltage of the driving transistor in the programming mode subsequent to an initialization mode.
